' RULINGAPPLIANCE.

Specification of Letters Patent.

Application filed January 25, 1906. Serial No. 297,848.

Patented Jan. 1, 1907';

I To-wll whom/ it mwyconcern:

Be it known that I,Lm)w1e HoLzER ANN, a citizenof theKingdomof. Belgium, and a resident of Antwerp, Belgium, (whose, postoffice address is Antwerp, 31 Longue Rue de l-Hospital,) haveinvented certain newand useful Improvements in Ruling Appliances,

Figure-1 is an elevation of the ruling device on; the spindle of which four rulii1gwheels and a: number of spacing-disks are shown. Fig. 2 is an elevation and part section of the guide, the central portion of which is removed in order to save space on. the drawing. Fig. 3 is a cross-section through. Fig. 2, drawn on an enlarged scale.

A is the ruling device, the spindle a. of which is of any suitable material and is preferably bushed at each endwith a'metallic lining b to receive the'two axes c c. The axis 0 has an extension c presenting a rectangular portion (1, and two terminal members h, hinged to it at f in such manner that they can be flapped back at right angles to the extension 0 andheld in thisposition, asshown in Fig. 3. 3

On the spindle a are mounted the rulingwheels m, by means of which the lines are drawn. These wheels m may be of any desirable compositionsuch as graphite, chalk, anilin-color mass, 850., pressed, molded, or turned, so as to present a suitable shape. The wheels may bemade thicker at the center than at the periphery. To render them stronger, they may be fixed on a central ring 1" or the like, through which the spindle a passes. When ananilin-colored composition of ready solubility is used to make the wheels m, the device may before ruling be drawn-across a damp felt blanket or pad, or a thin moist felt roller may be mounted on the device in such position that on ruling the marking-wheels m constantly rub against it,

whereby they receive a. uniform amount of moisture.

For the purpose of enabling lines to be ruled at any desired distance apart spacingdisks n of any suitable material'are mounted between the wheels m. There may be a considerable number of these disks n in thicknesses varying, for instance, from one to ten millimeters, so that any desired space can be provided between any two ruling.- wheels m.. The twosouter spacing-disks are provided with small set-screws 0 ando, re-

spectively, in order that they may be fixed onthe. spindle (1, whereby the position of all the intermediate wheels and disks on the spindle is-controlled;

pis the holder for the device, and it may be marked withmillimeter-divisions, so that the desired distances between the several ruling-wheels may bethe more readily adjusted.

In order to enable the wheels mend-spacing-disks nto be conveniently pushed over the spindle a or drawn off the same, the one end of the holder 19 may be tubular, and into it there may fit one shank ofaV bendx, the

other shank of which constitutes the axis 0. By drawing out the bend x the axis 0 leaves its bearing 6 and admitsof the required manipulation of the wheels-mand disks n. In stead ofthe employment of aslidingV bend m the bend may be hinged or pivotedso as to turn back.

: l The ruling device A isused in conjunction with the guide B. (Shownin Figs. 2 and 3.)

This guideconsists of a base-plate e, at the ends of which are the swivel-screws ii,which shown in the drawings, may be two bars provided with antifriction-balls Z. Between these bars 7c 7c there fits the rectangular portion d of the extension-piece 0 Fig. 1. In the drawings the balls Z are shown as protruding through apertures in the hollow bars 7c.

To use the appliance, the guide B must be laid at the left-hand side of the surface to be ruled, whereupon the end of the extensionpiece 0 must be inserted through the space between the bars k 76, so that the rectangular portion d'may lie between the two assemblages of balls Z. Hereupon the two wings h must be flapped back at right angles to the extension-piece 0 The ruling device Acan 4 Having thus described my invention, what i I claim as new, and desire to secure by Letters Patent, is

v 1. A ruling appliance, comprising a ruling device consisting of a holder, a spindle mounted therein and having a lateral extension on one end, and ruling-wheels mounted on the spindle, in combination with a guide to be arranged only on one-side of the surface to be ruled and presenting a race along which said extension travels, substantially as described.

2. A ruling appliance, comprising a ruling device consisting of a holder having a movcombination with a guide presenting a race along which the said spindle extension travels, substantially as described.

3. A ruling appliance, comprising a ruling device consisting of a holder having a bent member sliding telescopically at one end, a spindle, having a terminal extension, and carried at one end by the body of the holder and receiving at the other end one limb of the telescop1c member, and ruling-wheels mounted on the spindle in combination with a guide presenting a race along which the said spindle extension travels, substantially as described. a

4. A ruling appliance, comprising a ruling device consisting'of a holder marked with a scale, a spindle removably mounted in the holder and having a terminal extension, and ruling-wheels and spacing-disks mounted on the spindle, the two outer disks being provided with set-screws on their periphery; in

combination with a guide presenting a'race along which the said spindle extension travels, substantially as described.

, 5. A ruling appliance, comprisinga ruling device consisting of a holder, a spindle mounted therein and having a terminal extension which presents a rectangular portion and a terminal catch device, and rulingwheels mounted on the spindle; in combination with a guide presenting a race along which the rectangular portion of the spindle extension travels, being retained therein by the said catch device substantially as described.

6. A ruling appliance, oOrnprising a ruling device consisting of a holder, a spindle mounted therein and having a terminal extension which presents a rectangular portion and a terminal catch device, and rulingwheels mounted on the spindle in combination with a guide consisting of a base, swivelscrews at the ends thereof, and a race consisting of two parallel bars tapped terminally to receive the screws and receiving the rectangular portion of the said spindle extension between them, which latter is retained in position by the said catch device, substantially as described.

7. -A ruling appliance, comprising a ruling device consisting of a holder, a spindle mounted therein and having a terminal extension, which presents a rectangular portion and terminal hinged catches, and rulingwheels mounted on the spindle; in combination with a guide consisting of a base, swivelscrews at the ends thereof, andatrace consisting of two hollow parallel bars tapped terminally to receive the screws and having antifriction-balls projecting from their inner surfaces and receiving the rectangular portion of the said spindle extension between them, which latter is retained in position by the said catches, substantially as described.

The foregoing specification signed at Antwerp this 28th day of December, 1905.
